Referring to fig. 1-3, an embodiment of the present invention provides a building pile coring device, which includes a core drilling machine, a mounting frame 10, a positioning sleeve 20, a hanging assembly and a detection assembly 40.

The mounting frame 10 is used for being fixed above a pile foundation 100 to be cored, and is provided with a mounting hole 15, and the central axis of the mounting hole 15 is parallel to the central axis of the pile foundation 100; the suspension assembly is fixed on the mounting frame 10, the positioning sleeve 20 is suspended in the mounting hole 15 through the suspension assembly, the positioning sleeve is coaxially sleeved outside a drill rod 200 of the core drilling machine and can move on a plane perpendicular to the central axis of the mounting hole 15 along with the deflection of the drill rod 200, and the detection assembly 40 is used for detecting whether the positioning sleeve 20 deflects.

Therefore, when the core taking machine cores the pile foundation 100 through the drill rod 200, if the drill rod 200 has an offset condition, the positioning sleeve 20 is driven to offset on the mounting frame 10, so that the monitoring assembly of the embodiment can judge whether the drill rod 200 has an offset by detecting whether the positioning sleeve 20 has an offset; when the steel bar cage drilling tool is applied specifically, alarm devices such as an alarm lamp and a loudspeaker can be further arranged, when the positioning sleeve 20 is detected to deviate, the alarm device is triggered to alarm to warn constructors, so that the constructors can adjust the angle of the drill rod 200 in time, and the situation that the drill rod 200 continues to work when deviating and possibly drills the steel bar cage is avoided.

Specifically, as shown in fig. 3, the detecting assembly 40 includes a transmitting/receiving element 41 and a reflecting element 42, the transmitting/receiving element 41 is disposed on the mounting frame 10, the reflecting element 42 is disposed on the outer wall of the positioning sleeve 20 and is at the same height as the transmitting/receiving element 41, the transmitting/receiving element 41 is configured to emit incident light at a predetermined angle to irradiate on the reflecting element 42, the reflecting element 42 is configured to reflect the incident light to form reflected light, and the transmitting/receiving element 41 is further configured to receive the reflected light and convert the optical signal into an electrical signal, so as to determine whether the positioning sleeve 20 is offset according to the presence or absence of the electrical signal.

The detecting elements 40 are two groups, and the incident light angles of the emitting/receiving elements 41 of the two groups of detecting elements 40 are perpendicular to each other. The transmission/reception element 41 includes a light emitting diode and a photodiode. That is, the light emitting diode and the photodiode are integrated into a whole, incident light is emitted to the central axis of the positioning sleeve 20 through the light emitting diode, when the drill rod 200 is not deviated, the reflecting element 42 on the positioning sleeve 20 can emit the incident light to form reflected light, the reflected light is emitted into the photodiode, and the photodiode converts the optical signal of the reflected light into an electrical signal; when the drill rod 200 is deviated and drives the positioning sleeve 20 to deviate beyond a certain range, the reflection element 42 is staggered from the incident light, so that the incident light cannot be reflected to the photodiode, and the photodiode cannot convert the optical signal into an electrical signal; that is, when there is no electrical signal, it may be judged that the drill rod 200 is deviated by an angle exceeding a preset range.

The mounting frame 10 of this embodiment includes a ring 11 formed with a mounting hole 15, a frame 12 surrounding the ring 11, and a plurality of connecting beams 13 connecting the ring 11 and the frame 12, and the frame 12 is provided with a plurality of supporting legs 14, and the plurality of supporting legs 14 are fixed on the ground around the pile foundation 100. Specifically, when the mounting frame 10 is mounted and fixed, the mounting frame is mounted and fixed by a level, so that the circular ring 11, the connecting beam 13 and the frame 12 are in a horizontal state, and further, the central axis of the positioning sleeve 20 is parallel to the central axis of the pile foundation 100.

In one embodiment, the suspension assembly includes a plurality of mounting seats 30, the mounting seats 30 are fixed on the connecting beams 13 in a one-to-one correspondence manner, a first sliding block 33 and an elastic member 34 are slidably disposed in each mounting seat 30, one end of the elastic member 34 abuts against one end of the mounting seat 30, the other end abuts against the first sliding block 33, the first sliding block 33 is fixedly connected with a telescopic rod 31, one end of the telescopic rod 31, which is far away from the first sliding block 33, slidably extends out of the mounting seat 30 and is hinged to the positioning sleeve 20 through a hinge shaft 32, and the hinge shaft 32 is parallel to the central axis of the positioning sleeve 20. Preferably, the number of the connecting beams 13 is four, and the connecting beams are evenly distributed around the circumference of the circular ring 11, although in other embodiments, the number of the connecting beams 13 may be three, five or even more.

That is, the peripheral wall of the positioning sleeve 20 is suspended relative to the mounting seats 30 by the telescopic rods 31 hinged to the mounting seats 30, and when the drill rod 200 is deviated, the same deviation can be performed on the horizontal plane, and when the deviation exceeds a certain range, the detection assembly 40 can sense the deviation, so as to judge that the drill rod 200 is deviated. Most importantly, after the positioning sleeve 20 is deflected, the elastic acting force of the elastic member 34 in the mounting seat 30 in the direction corresponding to the deflection direction is increased, so as to provide a deviation rectifying acting force for the positioning sleeve 20, and the larger the deflection is, the larger the elastic acting force for the deviation rectification is, so that the positioning sleeve 20 has a certain deviation rectifying effect on the drill rod 200, and the possibility that the deflection angle of the drill rod 200 is continuously increased is reduced, so that the deflection angle of the drill rod 200 is kept within an acceptable range.

As shown in fig. 4, a horizontal bar-shaped hole 37 is formed in one end of the mounting seat 30 adjacent to the positioning sleeve 20, and the telescopic rod 31 extends into the mounting seat 30 through the bar-shaped hole 37. In this way, when the positioning sleeve 20 is deviated, the telescopic rod 31 not only extends and retracts relative to the mounting base 30, but also correspondingly moves in the strip-shaped hole 37, so that the positioning sleeve 20 moves in any direction on the horizontal plane under the action of the drill rod 200.

Furthermore, a second sliding block 35 is further slidably disposed in each mounting seat 30, an adjusting screw 36 is further in threaded connection with an end portion of the mounting seat 30 far away from the positioning sleeve 20, an end portion of the adjusting screw 36 extends into the mounting seat 30 and abuts against the second sliding block 35, and two ends of the elastic member 34 abut against between the first sliding block 33 and the second sliding block 35 respectively.

Thus, when the installation is started, the extension length of the telescopic rod 31 on each installation seat 30 can be correspondingly adjusted by adjusting the adjusting screw 36 of each installation seat 30, so that the central axis of the positioning sleeve 20 is aligned with the mark position of the pile foundation 100, and the installation and the positioning are more convenient and faster; in addition, in the process of coring, when the drill rod 200 deviates and exceeds a certain range, the adjusting screws 36 of one or more mounting seats 30 can be correspondingly adjusted to increase the elastic acting force of the elastic elements 34 in the mounting seats 30 in the deviation direction of the positioning sleeve 20 of the drill rod 200, so that the deviation rectifying acting force is improved, and the positioning sleeve 20 rectifies the drill rod 200.

Furthermore, in order to avoid that the difference between the outer diameter of the drill rod 200 and the inner diameter of the positioning sleeve 20 is too large, which results in an excessively large gap between the drill rod 200 and the positioning sleeve 20, and thus affects the misjudgment of the detection assembly 40 on the deflection angle of the drill rod 200, in the present embodiment, a plurality of positioning screws 21 are further disposed on the positioning sleeve 20, the positioning screws 21 are threadedly and threadedly disposed on the side wall of the positioning sleeve 20, and the plurality of positioning screws 21 are evenly distributed around the circumference of the central axis of the positioning sleeve 20. When the drill rod 200 is arranged in the positioning sleeve 20 in a penetrating manner, each positioning screw 21 is adjusted, so that the inner end of each positioning screw 21 is abutted against the outer wall of the drill rod 200, and the positioning sleeve 20 is ensured to be also offset when the drill rod 200 is offset.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

Above is the description to the technical scheme that the utility model provides, to technical personnel in the field, according to the utility model discloses the thought of embodiment all has the change part on concrete implementation and range of application, to sum up, this description content should not be understood as the restriction of the utility model.
